This solution may be useful if you observe time discrepancies such as the Duration status column for a service (incorrectly) showing +364 days or a graph displaying a time that is several hours in the future.

This type of discrepancy may be caused by inconsistent time zone configurations between the OS, database, PHP and the JVM.

  • Verify the time of the OS on the Uptime Infrastructure Monitor Monitoring Station and Database Server.
  • Login as the Uptime Infrastructure Monitor user and verify the time configuration of the Uptime Infrastructure Monitor database.

        • Create a file named time.php with the following content:
          Code Block
          languagesql
          <?php echo "current timestamp:" .time(); echo " current time: " .date("F j, Y, g:i a");?>
        • Save the file and browse to time.php to verify:
          Code Block
          languagesql
          http://<impactedhostname>:9999/time.php

      If all time zones tested above match your desired time zone and you continue to experience a time discrepancy, the issue is likely with the JVM. To force the JVM to a specific time zone, make the following change to the wrapper.conf (Windows) or uptime.lax (Linux) file: Image Removed

      • Append the following values to the additional parameters:
